sunday i went out with my stepson and son with a few other guys and went to a warehouse district for some street racing. of course i got called out and said sure, for me it's more for fun then anything else. 1st run i did was with a guy who has a stang with some upgrades and he beat me, now let me 1st state that i was pushing the alky button and it shuttered like they do before it launches, this lasted about 2 seconds so he got the jump on me from a 20 MPH start. he didn't pull away and i didn't gain on him, so my mistake and he even said what happened and i told him what i did. then my step son who has a simular setup and is always talking trash decided to try me, well he wasn't so lucky, i had him by 4 cars and was pulling. he said he couldn't get a bite but i wanted to know what are some of the most less costly ways to add HP to your car. what i have on the car is in my sig, incase your wanting to know. i've thought of twin turbo's or a bigger turbo. i don't want to add NOS as i'm not going to tear my engine up over that. if i lose i lose, but i still would like to make it faster and wanted some opinions.
